Introduction

Summer Upsell is a full-funnel upsell & cross-sell app for Shopify. It ships seven widget types — from product-page bundles to post-purchase offers — and a flat-pricing plan that doesn't scale with your revenue.

What's included

• 7 widget types covering every funnel stage: product page, cart, checkout, popup, and post-purchase.
• AI recommendations — both rule-based Basic AI (related / complementary) and our credit-based Summer AI powered by ChatGPT.
• Shopify-native discounts via Shopify Functions — no fake discount codes, no checkout hacks.
• Multi-language — per-locale overrides for widget title and button text.
• Detailed analytics — impressions, conversions, revenue, AOV lift per campaign.
• Auto-rotate non-performing campaigns (Pro plan).

How it works

1. Install the app from the Shopify App Store.
2. Enable the Summer Upsell app embed in your active theme.
3. Create a campaign in the admin — pick a widget type, trigger, and upsell source.
4. Add the matching theme block (e.g. Summer: FBT Bundle) to the page where you want it to render.
5. Publish — the storefront script picks up the campaign automatically.

Compatibility

• Shopify Online Store 2.0 themes (Dawn, Sense, Crave, Studio, Refresh, and most third-party 2.0 themes).
• Shopify Plus and standard Shopify plans.
• Multi-language stores via the Shopify Markets / Translate & Adapt locale system.
